b.) the amount of force with which the car pushes on the truck is smaller than that with which the truck pushes back on the car.
c.)the amount of force with which the car pushes on the truck is greater than that with which the truck pushes back on the car.
d.) the car pushes on the truck because its engine is running, while the truck without its engine running can exert no force on the car.
e.) neither exerts a force on the other. The truck moves forward because it it in the way of the car.
